This invention relates to an improved type of conical a aper cupconstructed of a blank similar in iorm to that covered in my Patent No.1,610,192, dated December 7, 1926. The cup of this invention is formedoi a quadrantal blank adapted to be formed upon coni cal rollers whichactto roll the blank and secure the overlapping edges together by meansof a cementitious material, said rollers constructed so that during theforming of a cup an arcuate edge of the blank is de fiected outwardlytoiorm a rounded edge or margin facilitating drinking from said cup. isan object of this invention to provide a conical paper cop the upperedge of which is bent outwardly during the forming of the cup to form aedge.

It is an important object of this invention to provide a conicaldrinking cup adapted to be constructed from a quadrantal blank by meansof conical formers or inandrels, one of which is provided with suitablemeans whereby the arcuate edge of theblank during the formation of thecup is deflected or rolled outwardly to provide a drinking lip or rimfacilitating drinking from said cup.

Other and further important objects of this invention will be apparentfrom the disclosures in the specification and the accompanying drawings.

This invention (in a preferred 1501111) is illustrated in the drawingsand hereinafter more fully described.

shown on the drawings: The p'aper cup comprises a cone 1 made cal manradial edge 3, and a substantially straight Figure 3 is an enlargedfragmentargisec- I of mandrel is adapted to coact. The cup is formedfrom a that illustrated 111 my Patent No. 1,610,192 and has an arcuateedge 2, a slightly curved seam forming edge 4, which is positioned at aconsiderable angle with respect to the radius and merges at one end witha curved edge of a projections?) which is used to reinforce the tip ofthe conical cup when formed; The

quadrantal hlanlr similar to conical forming mandrel is provided with aperipheral wire or head so positioned that when a blank is wound on theforming man- 7 drel, said wireor head will act on the arouate edge ormargin of the blank to roll or deflect the same outwardly to form adrinking edge or flange 6 shaped to conveniently lit over the lower lipof a person using the cup to facilitate drinking from the cup with outany danger of receiving a cut or ingury from a sharp straight edge ormargin often resulting horn use of cups having a straight drinking edge.The hlanlr is provided Witha'suitalole cementitious-material on aportion of one surface thereof, permitting the overlapping margins to hesecured together.

The important feature of the present conical cup resides in thenovelmanner in which the arcuate edge of the cup blank is rolled r ordefleted outwardly by means of the wire or head on the forming cone ormandrel dur- I ing the cup forming operation so that said arcuate edgeof the blank forms the deflected i 7 ing hem the cup. The rolleddrinking edge of the cup is adapted to he produced simply withoutnecessitating any crimping or bending over of the margin of the cupblank which forms the upper edge of the finished cup.

I am 'aware that many changes may he madeQand numerous details ofconstruction may be varied through a wide range without departing fromthe principles of this invention, and I therefore do not purposelimiting Fi ure 1 is a side elevation'ot a conical or mued'edge whichgreatly facilitates drink? l the patent granted hereon, otherwise thannecessitated by the prior art.

I claim as my invention:

A conical drinking cup constructed of'a' blank of substantiallyquadrantal form shaped to permit overlapping of two of the marginsthereof, and means for securing the overlapping margins together, saidquadrantal form having one edge thereof deflected during the formationof the cup to form a substantially plain peripheral drinking edge abovea curved section.

In testimony whereof I have hereunto subscribed my name at Chicago, CookCounty,

Illinois.
